Abstract

An apparatus for retaining vertebrae in a desired spatial relationship. The apparatus includes a fastener which cooperates with a connector assembly, a longitudinal member which is positionable along the spinal column at a location offset from the fastener, and a connector assembly which connects the fastener with the longitudinal member. The connector assembly includes a transverse member, a retainer block, and a set screw. The transverse member and retainer block have mating teeth. When the desired spatial relationship is achieved, the set screw is tightened thereby engaging the teeth and providing for a rigid locked assembly.
